Commonly known as Vulkollan, this highly specialized isocyanate was patented by Bayer Chemical and is widely regarded as a premium performance elastomer for the most demanding applications.

The NDI elastomer offers the elasticity of ether based materials and toughness of ester based elastomers. ÊItÊis the ideal choice in all application areas that call for exceptionally high resistance to wear combined with a high mechanical and dynamic load-bearing capacity.ÊVulkollan 93 and Vulkollan 97 have proven themselves in a variety of dynamic applications and have become the default elastomer for many high speed ride manufacturers.
